          More time and money is spent on nuclear power than
          any other form of energy. Yet its generating capacity –
          even with new reactors – and potential contribution to
          cutting greenhouse gasses, is much less than other
          methods. The funds should follow tried technologies
          offering greater returns.

                         continues to dominate the energy debate. This
                         is extremely unfortunate as this does not
                         reflect nuclear’s current or potential
                         contribution to the energy mix.
                             Nuclear power provides Britain with
          around eighteen percent of its electricity, nine percent of
          energy production, but just 3.5 percent of the final energy
          that is consumed. The difference between energy production
          and consumption results from the energy lost during
          transformation and transmission. For this source of
                                                                  POWER        result in only six percent of the required overall emissions

Description: According to the International Energy Agency's 2050 scenarios, to meet carbon dioxide reductions in line with an acceptable two degrees Celsius increase in mean global temperatures, the current use of nuclear power could be scaled up from around 370 gigawatts today to around 2,000 gigawatts.
